TREAD I ilOR TIRES).

Application filed March 27, 1913. Serial N o. 757,241.

Be it known that I, JOHN FRANCIS LE BARON, a citizen of the United States, residing at Chardon, in the county of Geauga and State of Ohio, have invented a new and useful Tread for Tires, of which the following is a specication.

l The device forming the subject matter of this applicat-ion is an auxiliary trea'd adapted to be applied to a vehicle tire, for the purpose of preventing the wheel from cutting into the soil, the device being intended, primarily., to permit an automobile or other vehicle to be used upon the yielding sandsof the sea-side or upon like unstable soils.

The invention aims to provide a tread of the sort described, which may be fashioned at small expense, the tread being so ccnstructed that it may be readily attached to .a vehicle wheel.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

With the above and other objectsv in view which will appear'as the description proceeds, the invention resides in the combination and arrangement of arts and in the details of construction hereinafter described plurality of slats 1, preferably, although not' necessarily fashioned `from hickory, or another tough wood, although obviously, metal may be employed in the making vof the slats 1 if desired. The'slats 1 are preferably disposed in parallel rel'tion and are spaced slightly apart. Certain of the slats. 1 are connected by braces 2 of approximately tri. angular -formythe inner faces of the braces 2 being rounded so as to conform to the periphery of the tire 4. The tire 4, it is to e understood, represents merely the periph. -ery of the'wheel, whatever maybe the'form.

. braces 2. with the slats 1 which lie upon thf braces. v,

The braces 2 may be recessed in their tread or outer portions as indicated at' 6, to receive straps 7 there being securing elements 8 passing through the braces 2 and the straps Those slats 1 which lie between the braces 2 are assembled with the straps 7 by means of sen curing elements 9. A securing device such as a pairof straps 10, is secured by screws 11 or otherwise' to the braces 2, the straps being connected by a buckle 14.

Iny practice, the entire circumference of the tire 4 is surrounded by the tread above described, the straps '7 atone end being provided with buckles l5 or like elements, whereby the shield may be held in annular form around the peri hery of the tire 4. The slats 1 at their en s extend beyond the by afforded, the construction being such that the vehicle may be run u on soft earth, without causing the wheels o the vehicle to sink into the earth.

When the occasion for the use of the tread has passed, the same may be disposed in a compact roll and maybe housed in small compass.

Having thus described the invention, what is claimed is 1. An auxiliary tread for a vehicle wheel comprising a plurality of slats' circumferentiallyspaced wheel engaging brace blocks assembled with certain of the slats only; and a connection between all ofthe slats,

l 2. An auxiliary treadfor alvehicle wheel comprising a plurality of slats; pairs of circumferentially fs ced Wheel enga ing brace blocks assemb ed with certain o the slats only; and wheel engagin means con. nected with the blocks of eac Ipair inde pendent-ly of the slats. e i

3. An auxiliary tread for a vehicle wheel, comprising a. plurality of slats lwheel-engaging braces mounted on certain ofthe slats; a flexible element extended transversely of the slats' and located between the braces and the slats; and securing elements uniting the braces, the flexible element, and the brace carrying slats.

4. An auxiliary tread' for a vehicle "wheel,

10 being extended beneath the rim 12v and sides of the tire 4, and a 'wide tread is therehaving a recess in its tead portion; a exias" my own, l have hereto afxed my sigheble element ocated in the recesses; and slats, tu're in the presence of two Witnesses. -certain of which are secured to the flexible element, others of which are secured to the JOHN FRANCIS LE BARON' 5 braces to hold the exble element in the Witnesses: lecesses.
